Flush Chrom{e,ium} DNS cache

If you're deploying things, you definitely were annoyed last time when you had to switch away from Chrome just to make sure the change was propagated.

But there's a way to clear off Chrome's host cache. I only discovered it today, so I'm recording it here:

  • Go to chrome://net-internals/#dns
  • Press the Clear host cache button. Quite obvious, right?

For the sake of completion, some GNU/Linux operating systems have a service called nscd that also needs to be restarted prior to this.

  • sysvinit based systems – sudo service nscd restart
  • systemd based systems – sudo systemctl restart nscd.service

That being written, have a nice migration! ;-)
